J., a corporation of New Jersey i. Application March 17, 1938, Serial No.-196,324r` reclaim. cl.. 11a-'262) This invention relates vto improvements in the methods of joining fabric-sections aridpin articles of manufacture having fabric-sections joined by stitched seams.

In the `manufacture of. high-.grade wearing' apparel and 'other articles, in. which the proximate margins of fabric-sections"l are united by.A stitchedseams, difficulty has been experienced1 heretofore in forming narrow joining.seams of finished appearance when said fabric-sections have cross-.seams i l l I The present invention has for its object to pro'- vide a simple ,method of securely joining the proximate margins `of fabric-sections,A whereby the joining seam has the requisite uniformity of appearance throughout the length thereof, and

whereby the raw edgesof the joined margins are effectively concealed.'

The inventionwlll be understood7 from the folrlowing description, .in connect-ion with the accompanying drawing whichI illustrates the improved method f joining fabric-sectionsand in which? 2 illustrates, in per'specnvennd partly 1nl Fig. ifrepres'ent's, perspective, two "fabricsections .having their.' overlapping marginsintial- -Iy united by ai row .of -fstraightaway stitches.

Fig. 4 illustrates, in perspective and partly in section, a finished seam formed by folding tand zigzag stitching the initially united fabric-sections ofl Fig. 3. Fig.- 5 represents, in perspective, two fabric-sections -having -overlapping margins initially joined byl a row of zigzag stitches. Flg. 6 illustrates, in perspective and partly in section, the finished seam formed by folding and stitching the initially united fabric-sections of Fig. 5. Fig. 'i illustrates, in perspective and partly in `section, a finished seam. corresponding to Fig. 4 but with the fold secured by two rows of straightaway stitches.

Referring to Fig. 1 of the drawing, fabricsections I and 2 having proximate margins thereof disposed in overlapping relation are initially united Lby a row of straightaway stitches 3, with the bodies of said fabric-sections extending in opposite directions" away from the united margins thereof. 'I'he uniting of the overlapping margins of the fabric-sections Land '2, as described, constitutes an initial stepin the joining of said fabric-sections, and the uniting stitches,

Fig. 3 representain-perspectiva "made by 'hand oriby machine, may be of any s'uitable'or preferred form.

Ans-shaped fold isthen formed in the initially united fabric-sections in a zone thereof to dispose the united ,margins between the outer plies 5 of thejold. In a preferred manner of forming this ys-snnned fold, the initially united margins are together inverted to overlie the fabric-section 2 by folding said fabricsection 2 on a line B-B at one side-of and substantially parallel 10 to the-row of stitches 3. Also, the fabric-section I risff'olded on a line A-A at lthe opposite side of and substantially parallel to the rowk of stitches. 3 to overlie said inverted margins. By thus folding the fanfic-secnnns, the portions thereof bel tween the lines A--A and B-'Bf i. e., the united marginsof said fabric-sections, are inverted between the fabric-sections to constitute the middle portion of the S- shaped fold illustrated in Fig. 2

of the drawing. l l 90 `I|This method of foldingthe fabric-sections has the advantage that the'body portions of said fabric-sections remain right side up, the united .margins only thereof being inverted. Furthermore, the preferred manner of folding the 25 Afabric-sections'may be conveniently effected by employing a sewingA machine provided rwith a well-known separable pleat-folder, one form of which is disclosed, for example, in the U. S. patent to W. Gibson, No. 930,469, Aug. 10, 1909. A 30 separable pleat-folderof this type not only facilit-ates handling of the work, 'but italso provides the requisite clearance for cross-seams while maintaining the desired fold-lines.

However, a similar effect may be obtained by 35 under folding the fabric section I on substantially the line A-A, Fig. 1, at one side of the row of stitches 3, whereby said fabric-section underlies the united margin of the other fabric-section 2, and by folding the fabric-section 2 on a line 4.0

',B-B, at the opposite side of the row of stitches 3, to overlie the margin of the fabric-section I.

-, andthat by any suitable ornamental covering-seam, as mi? be preferred.

Instead of initially joining overlapping margins of the fabric-sections, as in Fig. 1, the edges of the fabric-sections may be initially disposed in .abutting relationship. As illustratedin Fig. 3

l contactually overlies its margin and the mar-V gin lof the fabric-section 6, and so that the fabric-section 6 contactually underlies vits own margin and the margin of the fabric-section 5, a three-ply s-shaped fold will be formed as illustrated in Fig. 4 of the drawing. It will be noted that` the uniting stitches 1 are disposed inthe middle ply of Vthe S-shaped fold of Fig. 4 said stitches 'l are effectively concealed outer plies of the fold. 'The -threev plies ogy S-shaped fold of Fig. 4 are then secured *togetherby a row of zigzag stitches t, or they maybe secured together by two rows of straightaway sitches 9, Fig. 7, or otherwise as may be In Pig. 5 ofthe drawing, the proximate margins of two fabric-sections I0 and Il are disposed in overlapping relation and the overlapping margins are initially united by a. row of zigzag stitches II,v instead of by a straightaway row of stitches,

The fabric-sections I il as illustrated in Fig. 1. Y and .Il are then folded on the lines A-A and 3 8, in the same manner as in Fig. 2, the fold plies being secured together by a row of straightaway stitches Il.

It will therefore be understood that the present invention, in its broader aspects, is not limited to any specic means for initially uniting the fabric-sections, nor is it limited to any specific stitch-formation for securing together the fold plies. The primary purpose of initially uniting the fabric-sections is to facilitate the folding of the sections asv herein described, whereby the united edges of the fabrics and the initial uniting means are eifectually concealed.
